This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

What to Expect at the Emergency Room

Take the container with you to the hospital, if possible.

The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.

The person may receive:

• Blood and urine tests.
• Breathing support, including a tube through the mouth into the lungs, and a breathing machine (ventilator).
• Bronchoscopy -- camera placed down the throat to see burns in the airways and lungs.
• Chest x-ray.
• ECG (electrocardiogram, or heart tracing).
• Endoscopy -- camera placed down the throat to see burns in the esophagus and the stomach.
• Fluids through a vein (by IV).
• Medicines to treat symptoms.
• Surgery to remove burned skin.
• Washing of the skin (irrigation). This may need to be done every few hours for several days.

Outlook (Prognosis)

The outcome will depend on the extent of this damage.

Delayed injury may occur, including a hole forming in the throat, esophagus, or stomach. This can lead to severe bleeding and infection. Surgical procedures may be needed to correct these complications.

If the product gets in the eye, ulcers may develop in the cornea, the clear part of the eye. This can cause blindness.
